摘　　要：甚长基线双基地机载雷达是一种新的雷达配置模式,与普通的机载双基地雷达相比,它具有检测范围大、工作模式多等特点。在这种双基地雷达配置模式下,地面杂波呈现何种分布以及对空时自适应处理杂波抑制性能的影响有待研究。对甚长基线机载双基雷达的地杂波分布进行了研究,建立了杂波分布的一般模型,给出了杂波分布的具体表达式,分析了杂波分布与系统配置和检测距离之间的关系以及对空时自适应处理的影响。最后通过计算机仿真,验证了本文分析的正确性。Long baseline bistatic airborne radar is a new radar configuration mode.Comparing with bistatic radar,it has several advantages,such as wide detectable distance,various working modes.However,further study is required that what is the ground clutter distribution of the long baseline bistatic airborne radar configuration and how does the long baseline bistatic airborne radar configuration affect the space-time adaptive processing.An approach to the clutter distribution analysis of the long baseline bistatic airborne radar is proposed.Firstly,the clutter distribution analysis and the relationship among the configuration parameters are provided.Secondly,the relationship between the clutter distribution and bistatic radar system configuration and detection range is analyzed,and its influence on the space-time adaptive processing is also discussed.Finally,the computer simulation results show the validity of the proposed approach.
